A biscuit that survived the sinking of the Titanic has sold at auction for $23,000.

"You might say it’s the cracker that took the biscuit," auctioneer Alan Aldridge told The Washington Post this week, referencing a Britishism similar to "take the cake."

"I couldn’t imagine anything less appetizing, but if you’re in a rowing boat in the middle of the ocean, you’d certainly eat it with the rest of them," he added.

The 103-year-old biscuit measures 3.5 inches square, and has held up remarkably well over the years, after having made it off the ship in a lifeboat survival kit.

"The Spillers and Bakers 'Pilot' biscuit was kept as a souvenir by the Fenwick’s," the auction house wrote on its website, referencing James and Mabel Fenwick, newlyweds aboard the Titanic's rescue ship, the SS Carpathia.

"It was saved by Mr. Fenwick in a Kodak photographic envelope complete with original notation 'Pilot biscuit from Titanic lifeboat April 1912.'"

While Spillers and Bakers were famous in their day for making dog biscuits, Aldridge said it was "very much a human biscuit," similar to those seen in wartime as emergency rations.

The biscuit was sold to a collector in Greece.

Also at the auction was a photograph purporting to show the iceberg that sunk the Titanic, which sold for $32,200.
